The deaths of Banita Jacks' daughters prompted an investigation into D.C. Child and Family Services.
WASHINGTON -- A judge will consider whether a D.C. woman convicted of killing her four daughters and living with their decomposing bodies was improperly allowed to waive her insanity defense.
Defense lawyers are asking the judge to appoint an independent counsel to investigate Jacks' refusal to use an insanity defense.
The judge questioned the attorneys on Friday but is giving prosecutors time to add to their response. Another hearing is scheduled for Dec. 18.
U.S. marshals discovered the bodies of Jacks' daughters -- ages 5 to 16 -- in January 2008 when they went to evict her.
